SEPARABLE FASTENER.

Specification of Letters Patent. Patented A g. 9,192'L Application filed January '16, 19 20. 7 SerialNo'. 351,772.

To all whom it may concern: I

Be it known that I, LABS ANDREW LanssnN, a subject of the King of Norway, and a resident of Mattapan district, city of Boston, in the county of Suffolk and State of Massachusetts, have invented an Imt provement in separable Fasteners, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

This invention pertains toimprovements in separable fasteners, and morepartioularly, though not exclusively, to improvements in that class of separable fasteners wherein the stud and socket are separable by relative tipping movement in one direction only. 1

The present invention resembles some what that disclosed in my copending application, Serial No, 351,771, filed herewith.

In the drawings, which show an illustrative ,form of one preferred embodiment of my invention Figure 1 is a front elevation of a fastener secured to a portion of a curtain or other flexible fabric;

Fig. 2 is a section on the line 22 of Fig. 1'

Fig. 3 is a rear elevation of the socket;

and

Fig. 4 is an end elevation of a preferred .form of stud shown in the other figures.

Cooperating with this stud, I provide a socket which preferably includes a neckengaging plate 8 having an aperture therein through which the head of the stud can pass when compressed, the aperturepreferably being proportioned to the diameter of the neck of the stud so that, when the" stud is entered through the aperture, the stud resiliently engages the bottom of the neck. The stud-engaging plate is preferably, as shown, mounted on. the front face of the fabric, this being that side of the fabric away from the base of the stud.

On the opposite side of the fabric 9, I preferably provide a strain-receiving and limit iting plate 10, which-may include an ex- The socket may conveniently be attached to the fabric by prongs 12, which may project rearwardly from the plate 8, passing a through the fabric and through holes in the plate 10, being clenched over the back of said plate.

While I have shown and described a preferred form of one embodiment of my invention, it will be-understood that changes involving omission, substitution, alteration and reversal of parts, and even changes in the mode of operation, may be-made without departing from the scope of my invention, which is best defined in the following claims.

Claims l. A separable fastener comprising, in I combination, astudhaving a head and "a neck, and a springless socket, said socket providing on one side of the fabric means for engaging the neck ofsaid stud, and on ping movement of said stud and socket.

2. A separable fastener comprising, in combination, a stud having a head and a neck, a socket adapted to be carried by the fabric and providing on one side of the fabric a plate. having an aperture the perlphery of which fits the neck in the stud, and strain-receiving means on the opposite side of the fabric providing a bearing surface against one side of the stud. j

3. A separable fastener comprising, in

95 I the other side of the fabric means for limiting the direction of possible relative tipcombination, a stud having a head and a neck, a socket adapted to be carried by the fabric and providing on one side of the fabric a plate having an aperture the periphery of Which fits the neck in the stud, strain-receiving means on the opposite side of the fabric providing a bearing surface against one side of the stud and prongs projecting rearWardly from said plate, passing through the fabric, and clenched over 10 the part carrylng sald strain-receivlng LABS ANDREW LARSSEN.
